V3006. The object was created but it is not being used. The 'throw' keyword could be missing.

Dec. 14, 2015

The analyzer has detected a potential error when an instance of a class derived from 'System.Exception' is created but not being used in any way.

Here's an example of incorrect code:

public void DoSomething(int index)
{
  if (index < 0)
    new ArgumentOutOfRangeException(); 
  else
  ....
}

In this fragment, the 'throw' statement is missing, so executing this code will only result in creating an instance of a class derived from 'System.Exception' without it being used in any way, and the exception won't be generated. The correct version of this code should look something like this:

public void DoSomething(int index)
{
  if (index < 0)
    throw new ArgumentOutOfRangeException(); 
  else
  ....
}

This diagnostic is classified as:
